Question

Mr. McNeil decides to stop and buy dinner for the family too. He buys a pie of pizza for $12. He also buys 5 calzones for $3 each. Write one equation to describe the total amount he spends on the food. Explain how to use the order of operations to solve the equation.

Answer 1

12 + 5(3) = t

12 + 15 = t

27 = t

Explanation:

PEMDAS is the order of operations and states in what order to perform each operation.

Mr. McNeil's dinner is a pizza for 12 and 5 calzones at $3 each or 5(3).

Add the orders together and his equation is 12 + 5(3).

PEMDAS states to multiply before adding.

Multiply 5(3) = 15

Add 12 + 15 = 27

He spent $27.
